I've owned a Dankung Jungle Hunter II for more than a year. Right up front, I'll say I don't like the Dankung, but I do like the thin Chinese tubes. I plan to test a variety of configurations, and will use the Dankung because of the ease of changing tubes. To kick things off, here are the results I got from the original OEM bandset, which I assume were 1745.
Pull weight at 30 inches - 19 pounds
.375 lead ball (75 grains) - 192 fps avg 5 shots
.429 lead ball (115) grains - 182 fps avg 5 shots
.495 lead ball (175 grains) - 161 fps avg 5 shots
Note: all measurements were made with my computer and Audacity. Later I will compare the computer measurements against my Chrony.
* Velocity measured at my normal 34 inches draw.
Further testing will be with 1842 because that is what I have.
Now I'm going outside to make some Chrony measurements.
